. SPECIFICATION forming part of Letters` Patent No. 729,328, dated May 26, 1903. Y j n Application tiled September 4, 1902. Serial No.. 122,091. {No model To LZZ whom, t may concern.;-

Be it known that I, MILFRED L. GREEN- STREET, a citizen of the United States, and a resident of Owensville, in the county of Gasconade and State of Missouri, have invented.

a new and Improved Fluo-Stopper, of which the following is a'full, clear, and exact description. Y

This invention relates to a device which is adapted to be placed around a Hue so as to form when the stovepipe is removed a stopper completely closing the Iiue and which when the stovepipe is in place may be adjusted to t tightly around the pipe irrespective of the size thereof, providedLof course, that the size of the pipe is not beyond the maximum capacity ofthe device.

The invention comprises a collar with a' number of pivoted sector-like :sections arsections are thrown out into inactive position they lie back of the collar and do not appear, said sections being of such peculiar construc-.

' tion and relativearrangement that they may be readily moved inward to fittightly around a stovepipe or to extend completely over and close the central opening ofthe collar.

This specification isa specific description of one form of the invention, while the claim defines the actual scopethereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front view of the invention, showing by dotted lines-the folding sections moved partly inward to fit around and cover a relatively small stovepipe. Fig. 2 is a vertical section taken on the line 2.2 of Fig. 1, and Fig. 3 is an inside view'of thedevice.`

The collar is formed, preferably, of sheet metal and comprises a main portion a,'the outer periphery of which is formedwith an inward and thence outwardly extendingil'ange a', which is adapted to be fastened by tacks or like devicesto the wall in which the iiueopening b is formed. Referenceparticularly to Fig. 2 will show that this construction of the collar provides a cavity between the col- 5o lar and the wall, and in this cavity are arranged the above-referred-to swinging sectorlike sections. Said sections are formed of sheet metal, and each comprises anlinneredge c, curved concentrically to the inner periphery of the collar a, an outer edge o', curved yedge of the collar ct when the folding sections are moved outward, so as to limit the outward movement of the sections and so, also, as to lfurnish finger-grips facilitating moving the j .sections inward. ranged on its inner side, s o that when these When the folding sections of the device are thrown outward, they lie wholly back of the collar and nothing appears at the front eX- cepting the tongues or studs c4. To move the sections inward either to adj ust them around a stovepipe or to completely close the interior of the collar, it is only necessary to grasp the studs o4 and move the swinging sections toward the center ofthe device. Fig. l by dotted lines shows these sections moved partly inward. In this View the dotted lines e represent the stovepipe.

Various changes in the form, proportions, and minor detailsof my invention may be resorted to without departing from the spirit and scope thereof. Hence I consider myself entitled to all such variations as may lie within the scope of'my claim.

Having thus described my invention, I claim'as new and desire to secure by Let-ters The combination of a collar comprising a fromV the outer edge thereof, said flange being adapted to be connected to the supporting- 'bodyfportiom and ailange projecting inward surface, whereby to sustain the body of the collar projecting forward from said surface,'

a number of swinging segmental sections pivoted at the inner side of the body of the collar at their widened ends, and capable of moving outward behind the body of the collar so as to be concealed, and a tongue or stud at- In testimony whereof I have signed my tached to the inner edge of each section, said name to 'this specification in the presence of Io tonguesror studs being projected forwardly l two subscribing witnesses.

through the opening in the collar at the front 1 w 5 side thereof, the construction being such that MILF RED L' GREENSTREE the outward movement of the sections will Witnesses:

be limited by said studs, substantially as set ROBERT IRVING GRASS, forth. y NICHOLAS G. MATTHEWS.
